Answer:
B, E, F, G
Explanation:
Subscetable is an incorrect spelling, the correct spelling is susceptible, and it means being open to or easily influenced by a thing.
Property in this context is incorrect, the correct word here is 'properly' which can be interpreted as 'in right manner'.
Can't is an abbreviation for cannot, and in a formal writing it is best to use the full form of a word rather than the abbreviation, therefore i would use the word 'cannot' in place of can't.
Unbeneficial is a controversial word yet to well incorporated in the vocabulary, it raises a question in the sentence. I would replace it with 'disadvantageous, unhelpful or unprofitable', because these words will be better understood in this context.
